Mysqldump: Couldn't execute 'show events': Cannot proceed because system tables used by Event Schedu solution

Recently, the old version of mysql instance is poured into percona 5.5.30, which uses online full Backup. as a result, the tables in the mysql database are also poured into the instance. this is a tragedy and backup reports an error.

There is no way to reverse the data in the mysql database, clear it, and then import it to the percona table structure. In the end, it will not work if you need to restart the database properly...

You can only enable the switchover, and the master and slave nodes can be switched from one channel to the other and restarted.
